Finland Broad Scope Tender

The technology group Wrtsil has been selected to supply an integrated propulsion and dynamic positioning thruster solution including the engines a Wrtsil NOx reducer emission abatement system as well as steerable and tunnel thrusters to deliver optimum performance for vessel dynamic positioning in this new wind turbine installation vessel WTIV. The ship is being built at the China Merchants Heavy Industry Jiangsu Co yard for Norwegian heavy transport and WTG installation contractor OHT ASA and is the first of two next-generation WTIVs to be added to the OHT fleet. The order with Wrtsil was placed in May 2021. The GustoMSC NG-14000XL-G design jack-up vessel is customised for offshore wind turbine installation and XL monopile foundations. The vessel will feature a telescopic crane with a maximum capacity of 2500t and a maximum lifting height of approximately 165 metres. The compact design of the Wrtsil thrusters is an important benefit since the weight of all onboard equipment can be critical for a jack-up vessel. The lightweight Wrtsil thruster package meets this requirement while delivering excellent station-keeping capability. There is rapid growth in demand for the installation of offshore wind turbines and the vessels designed to carry out this construction work need to be state-of-the-art. The same applies to the propulsion solutions because reliable and efficient dynamic positioning is essential in all sea conditions. The full scope of Wrtsil solutions will provide the operational and environmental performance demanded for the next-generation market says Torben Mikkelsen OHTs Newbuild Project Manager.The aim is always to provide optimal propulsion performance for efficient vessel operations and the advanced range of Wrtsil solutions selected for this ship will do just that. By enabling efficient free sailing and outstanding dynamic positioning we are at the same time contributing to the decarbonisation of shipping says Dirk Folchert Senior Sales Manager Wrtsil Marine Power. The Wrtsil scope includes four Wrtsil 32 and two Wrtsil 20 engines the Wrtsil NOx reducer NOR system five steerable thrusters and one Wrtsil tunnel thruster. Delivery to the yard will take place during the first half of 2022. The ship is expected to be delivered during the second quarter of 2023. Effective station-keeping is enhanced by the thrusters proven retractable system which has an energy efficient 8-degree tilting feature. This reduces the power need and therefore also fuel consumption. The thrusters also deliver thrust that can be up to 23 percent more effective than non-tilted units. The Wrtsil steerable thrusters feature a modern electric steering system to provide higher redundancy reliability and a lower lifecycle cost.
